The cylindrical scction 17 of the bar 11 is of a lengthsuiiicient to compensate for any irregularity in the alinement of theboxes 15 on the car 16, and when the latter has been moved to properposition, the free end of the charging` bar will be elevated to lift theboi; 15 from the car and then moved forwardly or toward the furnace 8 tocarry the box into the latter, and is then turned7 in the usual and Wellknown manner to deposit the contents of the box into the furnace.

After the contents of the box has been deposited in the furnace, theboi; is withdrawn by the rearward movement of the charging bar anddeposited on the car 16. If ther JoXes are to be discharged into thesame furnace the changingbar is disengaged from the empty bei; andconnected up with a filled box and the car 16 moved as previouslyexplained until the filled box is opposite the furnace door and isdischarged as above enplained. After all the boxes have been emptied theear 16 with the empty boxes thereon is moved to a point Where the latterare to be refilled and the operation repeated.

It vvill be seen however that When the car 16 carrying the boxes is tobe shifted, the charging bar is supported adjacent its free end in thesaddle 12 and all side thrust on the bar is transmitted from the saddledirectly to the truck frame 13 instead of through the bar to thecarrying` frame 9 of the latter and from there to frame It is evidentthat many slight changes might be resorted to in the relativearrangement of parts shown and described Without departing from thespirit and scope of my invention hence I would have it understood that Ido not Wish to confine myself to the exact construction and arrangementof parts shown and described but,

Having` fully described my invention what I claim as new and desire tosecure by Letters Patent, is

1. In a furnace charging apparatus, the combination of a main frame, aframe carrying a charging hanl the latter adapted to have a verticalmovement at its free end whereby it ma7 be enga-ged with and disAengaged from the socketed end of a charging;

box, the said charging bar carrjing frame being mounted to move in adirection at right angles to the traversing movement of intenses saidmainframe, and a. seat on the mainframe adapted to receive the chargingbar and form side supports for 'he free end of the same.

Q. In a furnace charging' apparatus, the combination of a main frame, a.charging bar carrying framel mounted to move thereon in a direction atright angles to the traversing; movement of the main fra-me, a charging4bar carried by said charging bar frame and adapted to have a verticalmovenient at its free end whereby it maybe engagged with or bedisengaged from a chargingbox, and a recessed seat secured to the outerend of said main frame and adapted to receive and form. side supportsfor he free end of said charging bar.

3. In a furnace charging apparatus, the combination of a main frame, acharging bar carrying frame mounted to move in a direction at rightangles to the traversing movement of said main frame, a charging barcarried by said charging bar frame and adapted to have a verticalmovement at its free end whereby it may be engaged with or disengagedfrom a charging bozn and a. recessed seat secured to the frontend of themain frame and adapted to laterally support the free end of the chargingbar.

ll. In a furnace charging apparatus, the combination of a main frame, acharibar mounted to move'in a direction at right angles to thetraversing movement of said frame, the said bar being provided adjacentits free end with an enlarged cylindrical seetion and a recessed seatadapted to receive said enlarged portion of the bar and form a lateralsupport for the free end of the bar.

In a furnace charging apparatus, the combination of a main frame, a.tapering` charging bar mounte l to move in a direction at right anglesto the traversing` movement of the frame and provided near its smallerfree end with a cylindrical portion, and a recessed seat on the frontend of the main frame adapted to receive and closely embrace thecylindrical portion of the charging; bar and form side supports orabutments for thelatter.

In testimony whereof`r I have signed this specification in the presenceof a subscribing witness.
